' 'o aZZ fte/'tom t muy conce/m Be it known that I, SIDNEY' Mnwonrt, a citizen ofthe United States, residing at llfilson, in the county of l,Wilson and State of North Carolina, have invented certain new and useful mprovernents in Loose Leaf Binders, of which the following` is a specification.

My invention relates to improvements in loose leaf binders.'

An important object of the invention is to provide a device for detachably holding the loose leaves, which device is longitudinally adjustable to lit leaves of different lengths, with the rings or holding elements independently longitudinally adjustable, so that they may properly register with the openings formed in the leaves.

A further object of the invention is to simplify the construction of the holding elements, rendering them cheaper to manufacture and more reliable in operation.

Other objects and advantages of the 3invention will be apparent during the course of the following description.

1n the accompanying drawings forming a part of this specification and in which. like numerals are employed to designate like parts throughout the same,

Figure 1 is a horizontal sectional view taken on line 1-1 of Figure 2,

Figure 2 is a vertical longitudinal sectional view taken on line 2 2 of Figure 1,

Figure 3 is a transverse vertical sectional view taken on line 3-3 of Figure 2,

ll1 igure l is a plan view of one of the holding elements, and,

Figure 5 is an end elevation of the same.

.ln the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral designates a cover, embodying sides 11, foldable at 12 upon a back 13. rlhis cover may be of any well known or preferred construction.

The holding device embodies an adjustable base, including base-guides 141, which are curved in cross-section, as clearly illustrated in Figure 1. These base-guides are j provided at their longitudinal edges with over-hanging flanges 15. The base-guides 1d are formed separate and are therefore adjustable longitudinally toward and away from each other, corresponding to the length of the cover 10, or the leaves 16. The baseguides let may be attached to the bank 15 remain connected.

serial no. 612,996.

ofthe cover, by any suitable means, and as illustrating one form of means, ll have shown attaching elements 17, in the form of McGill fasteners, which pass through apelements, as any other suitable form of means may be employed.

lf preferably provide three separate holding devices, which are individually longitudinally adjustable within the guidebases rlhese holdingdevices embody bases 18, slidably mounted within the base-guides 14. The intermediate base 18 spans the space between the inner ends of the base-guides, and also serves to connect these base-guides. rlhe intermediate base provides means whereby the base-guides 1e may be longitudinally adjusted with respect to each others and @f course the intermediate base 18 may also be shifted longitudinally with respect to the base-guides, as is the case with the outer base 18. Each base 18, Figure l, is curved in cross-section,

and is provided at its edges with inwardly extending curved flanges 19, slidable within the flanges 15. The base-guides le and the base 18, both beingcurved in crosssection, are suitably stiff and resilient, transversely.

Each base 18 carries a ring or loop 2U, which embodies two sections 2l. Each section 2l is formed of suitably still wire, bent to` forni a loop element 22. The wire is then bent at the point 23, forming a l1- shaped foot 241;, in luding an inner arm, 25, projecting` longitudiiuilly beyond the point 23. ll he inner arms of these teet are in permanent contact, and are pivotally bound together by a sleeve or clip 2G, placed thereon, as shown. rl`he base-guide ll and base 18, which are hollow., face in opposite directions, and hence j novide ample space, fo receiving the feet 24 and associated elements.

Vln the use of tue holder, the base-guides 14; are First suitably longitudinally adjusted upon the back 1? and are then secured thereto by meu-ns of the attaching elements 17. The bases 18 are carried within these base-guides. lll/*hen the loose leaves 1G are presented to the holding devices, should the loopsv 21 not properly register with the openings in the leaves, the base or bases .will be seen that I have provided a holding device for loose leaves, Whichpossesses a large range of adjustability, is highly convenient in use, and reliable in operation.

It is to be understood that the form of `my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to Without departing fromthe spirit of my invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. In a loose leaf binder, a cover having a back, a plurality of base-guides adapted to, be vlongitudinally adjustably' mounted upon the back and to be secured thereto in a selected adjust-ed position, a plurality of bases longitudinally adjustably mounted Within the base guides, Aand holding elements carried by the bases.

2. In a loose leaf binder, a cover having a back, a pair of base guides adapted to be adjusted longitudinally upon the back and to be secured thereto in` a selected adjusted position, an intermediate base spanning the inner ends of the base-guides and being longitudinally adjustable therein, and bases longitudinally adjustably vmounted within the base-guides outwardly of the intermediate base, and holding` elements carried by the bases.

3. In a loose-leaf binder, a cover having a back, a pair of base-guides, an intermediate base telescoping the inner ends of the base-guides` outer bases telescoping the outer endsof the base-guides, holding elements carried by the bases, and means for attaching the baseguides to the back.

4. In a loose-leaf binder, a pair of baseguides, a base teleseoping with the inner ends of the base-guides, outer bases teleseoping with the outer ends of the base-guides, and holding elements carried by rthe bases.

In testimony whereof I aix my signature.

SIDNEY G. MEIVBORN.
